Application filed July 21, 1925. Serial No 45,003.

that shall adapt the machine for the manufacture of heels of the above-described character. Other and further objects will be- 1 explained hereinafter and will be particularly pointed out in the appended claims.

In the accompanying drawings, Fig. 1 is a plan of a heel adapted to be manufactured by the machine. of the present invention;

Fig. 2 is a section taken upon the line 2-2 of Fig. 1, looking in the direction of the arrows; Fig. 3 is a side elevation of a machine constructed according to a'preferred embodiment of the present invention; Fig.

4 is a plan of the same; Fig. 5 is an end elevation of the'same; and Fig. 6 is a section taken upon the line 66 of Fig. 3, looking in the direction of the arrows.

A wood-heel block 2 is adapted to be clamped between a relatively stationary jaw,

4 and a relatively movable jaw 6, as shown more particularlyin Fig. 3. The jaws 4 and 6 are carried uponanarm8that is pivoted at 10 to an upstanding portion 12 of the frame of the machine. The arm is thus pivoted about the pivot 10 so as to move the heel block 2 along the arc of a circle whose center is the pivot 10 into the-path of operation of a rotary .knife 14. The knife is V so shaped, as shown more particularly in- Figs. 5 and6, as to cut a'concave groove in the block 2. The groove'is indicatedin Fig.

1 by the concave hnes 16 and 18. Owing to the convexity of the path of travel of the block 2 past the cutter, however, the coilcave groove will be cut in the block 2 along a convex curve.

made adjustable vertically in any well 80 known way in order that its distance from the cutter.14 may be varied, and the convexity of the curve 20, therefore, changed. In

\ thedrawings this adjustment is illustrated The convex curve is indi-. cated in Fig. 2 at 20. The, pivot 10 may be I as effected by moving the pivot bolt 10 into ahigher or lower bolt-receiving opening 21.

In order to actuate the arm 8 about its pivbtlO, it is connected with a sliding member 22 by means of a pin 24 that is fixed in thearm 8 and that is slidably mounted in a vertically disposed slot 26 of the slide 22.

As the slide is moved back and forth by means of a handle 28, therefore, the arm 8 will be caused to pivot back and forth about its pivot 10. A catch 30 is designed to lock the sliding'member 22 against sliding movement. The catch 30 may be released to permit movement of the sliding member 22. but is normally held in position to lock the slide against movement by a'spring 32 Rolls 34 or other antifriction means may be provided upon the slide 22 and resting upon the frantic of the machine to facilitate the sliding movement of the 'sliding member22.

In order to adjust the convexity and the position of the curve 20, the jaws 4 and 6 are made adjustable upon the arm 8. The

jaw 4 is pivotally adjustable about a pivot 36 to rovide for different bevels orangles at which the heel breast may be presented to the cutter. The jaw 4 may be locked in pivotally adjusted position by means of a screw threaded member 40, pivoted to the jaw 4 at 42, and locked in threadedly adjusted position by lock nuts 44. The jaw 4, the member 40, the pivot 42 and lock nuts 44 may be pivotally adjusted as a unit about a pivot 38.

This pivot 38 may take the Zform of two.

screws extending inward toward each other from opposite'd-irectidns "and having pivot points set nto the block The jaw 6 is ad justable by means'of a slot and-pin arrangement 46, 48 and is provided witha tongue 47 by which it is guided in a groove formed in the cover that is secured in place by screws 49 The jaw 6 is adapted to clamp the block 2'against the jaw 4 by a screwvthreaded member 50, threaded through one end of a lever 52 intermediately pivoted at 54, and the'other end of which is loosely pivoted to the tongue member 47 of the jaw 6 at 56.. The screw-threaded member50 is adapted to actuate the lever 52 about the pivot 54,, in opposition to a spring 58, by

engaging a lug 60. A rest or gage 62 is adjustable by means of a in'-and-slot arrangement .64, 66, for adjusting the position 2 i I ose 77s occupied by the face of the block opposed to .the breast. As the gage 62 is adjusted in or out, it provides for positioning the heel block 2 nearer to or further from the pivot 10, thus forming an additional means for adjusting the distance of the block from the cutter. A finer range of adjustment is thus provided than with the openings 21.

A very important feature of the present invention resides in its applicability as an attachment to standard breasting or grooving machines provided with cutters 14, slides 22, and standard frame table 68 mounted upon legs 70. All that is necessary is to provide such standard machines with the upstanding portion 12,'pivot 10, and other related parts, as will be obvious to persons skilled in the art.

What is claimed is:

1. A machine of the class described hav ing, in combination, two elements, one of the elements comprising means for clamping an article, the other element comprising a knife shaped to cut a groove in the article, a sliding member, and means connecting the sliding member with one of the'elements to effect a movement of the said one element in a curved path adjacent to the other element in response to a sliding movement of the sliding member, whereby the groove is cut in the article along a curve.

2. A machine of the class described having, in combination, means for clamping an article, a rotary knife shaped to out a concave groove in the article, a sliding member, and means connecting the sliding member with the clamping means to effect a movement of the clamped, article in a convex path into the path of operation of the knife in response to a sliding movement of the sliding member, whereby the concave groove is cut in the article along a convex curve.

3. A machine for grooving heels having, in combination, two elements, one of the elements comprising means for clamping a heel blank, the other element comprising a knife shaped to cut a groove in the heel blank, a sliding member, and means connecting the sliding member with one of the elements to effect a movement of the said one element in a curved path adjacent to the other element in response to a sliding movement of the sliding member. whereby the groove is out in the heel blank along a curve.

4. A machine for grooving heels having,

in combination, means for clamping a-heel .blank, a rotary knife shaped to cut a con-.

cave groove in the heel blank, a sliding member, and means connecting the sliding memher with the clamping means to efi'ect a movement of the clamped heel blank in a convex path into the path of operation of rotary knife shaped to cut a concave groove in the heel blank, a sliding member, and means connecting the sliding member with the arm to effect a movement of the clamped heel blank in a convex path into the path of operation of the knife in response to a sliding movement of the sliding member, whereby the concave groove is cut in the heel blank along a convex curve.

6. A machine as defined in claim 5 in which the pivot is adjustable to adjust the convexity of the convex curve.

7. A machine as defined in claim 5 provided with meansfor locking the sliding member against slidingmovement.

8. An attachment for a heel-blank-grooving machine provided with a rotary knife shaped to cut a concave groove in a heel blank, a heel-blank clamp and a sliding member for actuating the-clamped heel blank into the path of operation of the knife, the

said attachment comprising a pivoted arm upon which the clamp is mounted, and means connecting the sliding member withthe arm to effect a movement of the clamped heel blank in a convex path into the path of operation of the cutter in response to a sliding movement of the sliding member, whereby the concave groove is cut in the heel blank along a. convex curve.

9. An attachment fora h'eel-blank-groow ing machine provided with a rotary knife shaped to cut a concave groove in a heel blank, a heel-blank clamp and a member for actuating the clamped heel blank into the path of operation of the knife, the said attachmen't comprising a pivoted arm upon which the clamp is mounted, and means connecting the member with the arm to effect a movement of the clamped heel blank in a convex'p'ath into the path of operation of the cutter. in response to a movement of the member, whereby the concave groove is cut in the heel blank along a convex curve.

In testimony whereof, I have hereunto subscribed my name.
